🌋 Sixty million years ago, a mantle plume beneath the North Atlantic triggered extensive volcanic activity—leaving behind iconic sites like the Giant’s Causeway & Fingal’s Cave🌋 New research explains why: thinner patches in Earth’s lithosphere funnelled the plume’s hot rocks far and wide.

What’s the story behind this fascinating rock? It is laminated layers of shales and jaspers found in North West Queensland, Australia, formed 500 million years ago. These colourful layers do not align because they have been faulted (fractured and displaced). #TectonicTuesday #Faulting #Geology
A museum staff member holding the rock up in front of a wall of 13 other rocks. The specific specimen is a deep/purple colour with fine layers of red/orange colour too. The layers are displaced. A close up of the rock where you can see the layers in more detail. They are extremely fine , hence the term 'laminated' is used.
